Question: Prove that the channel thermal noise of a MOSFET can be referred to the gate as a voltage given by 4kTϒ/gm. As shown in Fig, the two circuits must generate the same current with the same terminal voltages.
Design a second-order banpass filter with center frequency f=10. The gain should be zero at t=0 and t= 8. Select poles at -a ±j10. Explain the influence of a on the frequency response.
Each player has 8 switches that have a value of 0 to 7 and the game has a 3-bit counter that will generate a random number between 0 and 7. The player that can come as close a possible to the random number
Obtain a minimized equation for the function F(X,Y,Z)=Σ(0,1,3) + Σmd(5,6,7) then draw a schematic to implement the minimized function in SOP form using AND, OR and inverters. Draw a schematic implementing the function using only NOR and inverters.
A certain sample of pure quartz has a dielectric constant of 3.8, dielectric strength of 1.0 kV/0.0010 in, and a density of 2.6 Mg/m3. Assume the number density of dipoles in quartz is the same as the number density of SiO2 units.
calculate the convolution (x1[x]*x2[k]) for the following pairs of sequences: a-) x1[k]=u[k+3]-u[k-2] and x2[k]=u[k+5]-u[k-4] b-) x1[k]=0.5^k u[k] and x2[k]=cos Pi*k u[-k]
Find a set of basis functions for this signaling scheme. What is the dimension of the signal space? Express si(t) in terms of these basis functions and the signal energy, E = A2/2.
Voltage and current measurement taken for a 3- phase Wye- connected alternator indicate a line voltage of 208 V and a line current of 20 A. What is the value of the phase voltage and phase current
